Hi, and thank heaven for GDAL! I was so happy to find this tool, but I am having some trouble figuring out the exact command I need for an image warping application. If there is someone who doesn't mind a newbie type question, I could really use the help!
Essentially, I have imagery which is referenced with British National Grid. I am tyring to convert / warp this so that it can be used within Google Earth. I have reference points for the upper left and lower right of the image in Easting and Northing, and transformed those so that I got lat / long coordinates which line up very well within Google Earth, however it appears that the projection is off. I am hoping to use gdalwarp to convert the TIF file (referenced as mentioned), but I had some questions: - For the world file that I create for gdalwarp, should I include the Easting / Northing, or does this need to be lat / long? - Can I just go straight to gdalwarp, or do I need to do some other translation first? - The command I am trying to use looks like this: gdalwarp -s_srs "proj=utm +zone=33v +datum=OSGB36" -t_srs "proj=latlong +datum=WGS84" filein.tif out.tif Is this the correct command to get from a BNG source ortho image to what would overlay correctly in something like Google Earth? Many thanks for any help! -Scott -- View this message in context: http://n2.nabble.com/gdal-dev-GDAL-for-BNG-to-Lat-Long-WGS84-tp4652000p4652000.html Sent from the GDAL - Dev mailing list archive at Nabble.com. _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
